Mystical Duality: Allegory of God’s Nature

The symbolism described in some cited sources points more to the mystical unity and dual nature of God than to an assertion of His national or ethnic origin. The depictions of the Divinity as both Father and Mother, with the merging of the image of the Holy Spirit and the figure of the mother (for example, Mary), serve to reflect a profound mysterious nature in which traditional gender categories complement each other.

For example, one excerpt from file link txt states:
"‘You are the bridegroom of my blood… bridegroom of blood according to circumcision,’ says to his son Sephora, wife of Moses (Ex. IV, 26). ‘Your Creator is your spouse… As a wife, the Lord calls you,’ says the prophet to Israel (Isa. LIV, 1–6). Israel is the Bridegroom and the Bride, betrothed to God, He and She – Man-Woman."
This quotation employs symbolism related to the Jewish covenant ritual of circumcision and the relationship between God and the chosen people, which rather illustrates the relationship between God and the Jewish people than provides grounds to consider God as ethnically Jewish by origin.

Another example can be seen in the description of the dual nature of Divinity from file link txt, which emphasizes that:
"God is simultaneously 'father' and 'mother.'"
This statement indicates that, in order to grasp the deep mysteries of Divinity, symbols are traditionally attributed to both gender categories, emphasizing the universality and all-encompassing nature of His essence, but it does not imply affiliation with any specific nation.

Thus, despite the use of Jewish symbolism (for example, through the ritual of circumcision) and the image of motherhood, these texts do not substantiate the idea that God has Jewish origin. They present an allegorical and symbolic description of the relationship between God and people, particularly with the chosen people, rather than addressing His ethnic belonging.
